Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
(2E,​4E)​-3-​Methyl-​5-​[(2S,​3S)​-​3-​methyl-​3-​(4-​methyl-​3-​penten-​1-​yl)​-​2-​oxiranyl]​-2,​4-​pentadienoic Acid Methyl Ester (CAS 153651-93-5) is a high-purity analytical reference standard with the molecular formula C16H24O3 and a molecular weight of 264.36 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (2E,​4E)​-3-​Methyl-​5-​[(2S,​3S)​-​3-​methyl-​3-​(4-​methyl-​3-​penten-​1-​yl)​-​2-​oxiranyl]​-2,​4-​pentadienoic Acid Methyl Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
